Production of biogas from biogenic residues for local energy supply

Biogas is an alternative sustainable energy resource because it is produced from renew-able resources as well as biogenic waste. Renewable resources are nearly CO₂-neutral because they are consuming CO₂ during growing. On the other hand the dependence on fossil fuels is reduced by energy production from biomass and the cultivation of re-newable resources opens up an employment perspective for the European agriculture. Biogas is produced by fermentation of biomass. The use of biomass is limited by high concentration of harmful gases like H₂S as well as inert gas like CO₂.
